Outcomes following endoscopic-assisted Woodward procedure for Sprengel deformity.

Abstract

An endoscopic-assisted approach for Sprengel deformity has been previously reported. Our objective was to assess outcomes of the endoscopic Woodward procedure in a series of patients. Retrospective analysis was performed of children with a Sprengel deformity treated between November 2014 and February 2018. Recorded data were demographic, pre- and postoperative active shoulder elevation and deformity severity according to Cavendish. A total of 12 children (four girls and eight boys, ten right-sided/two left-sided) with a mean age of nine years two months (3 years 5 months to 16 years 1 month) and mean follow-up 19.8 months (10 to 48) were assessed. Nine children were classified as Cavendish Grade III and three as grade IV, respectively. Mean preoperative active shoulder forward elevation was 100.8° (70° to 120°), while postoperatively it increased to 149.2° (100° to 170°). Mean preoperative scapular high difference was 4.5 cm (2.8 to 5.2), while postoperatively it was 1.33 cm (0 to 2.8). The endoscopic assisted Woodward procedure is an effective technique. Further comparative studies will ascertain advantages in functional and cosmetic results compared to the standard Woodward procedure. Therapeutic study, Level IV.
